Replaces instances of "recent topics" in the web-app and documentation
to be "recent conversations".
Renames both `recent-topics.md` files in the help center to be
`recent-conversations.md` and updates/redirects links to new URL.
Does not update instances of "recent topics" in frontend code comments
and does not update the main overview changelog, for now.
Does not change case study text where "recent topics" was referenced
in a quote, but does change generic text references to be "recent
conversations".
Updates references to keyboard keys in the help center docs to use
`<kbd>` HTML elements, which also means updating them to be as the
key would appear on a keyboard.
Previously, uppercase and lowercase letters were used to indicate
when/if the `Shift` key was being used, and even that was not
consistent throughout the documentation.
For CSS styling, adds a similar rule for `<kbd>` elements that is
used in `/static/styles/app_components.css`. And updates the CSS
class used in `/static/js/portico/help.js` for `adjust_mac_shortcuts`
accordingly.
Also, takes advantage of revising these pages for making small
updates for current help center documentation practices.
Fixes existing errors in the help center documentation where a
keyboard shortcut that has multiple keys is all one inline code
tag (e.g. `Ctrl + [`) instead of being separated into individual
inline code tags for each key (e.g. `Ctrl` + `[`).
Add `escape_navigates_to_default_view` as a bool setting in
UserBaseSettings model and implement it as a checkbox that toggles
the hotkey implementation of escape to the default view in the
advanced user display settings.
With /help/ documentation edits from Alya Abbott.
Fixes#20043.
